BOOK-BINDING.

SPECIFICATION forming part of Letters Patent No. 286,254, dated October 9, 1883,

Application filed January 7, 1882. (Model) To aZZ whom, it may concern:

Be it known that 1, WILLIAM IRELAND BLAOKMAN, a citizen of the United States, residing at Columbus, in the county of Lowndes and State of Mississippi, have invented a new and useful improvement in Book-Binding, of which the following is a specification.

My improvement relates to that class of books in which binding-wires inserted lengthwise with the folds of the signatures are used, and the object is to prevent thewires from being accidentally drawn out and to facilitate the insertion through the saw-cuts of the backcords for securing the signatures together. I accomplish this object by making bends or curves in the binding-wires equal in number to the saw-cuts in the backs of the signatures, and in such position as to register with them when the wires are laid in the folds of the signatures, the bends projecting sufficiently to admit the easy insertion of the needles,to which the back-cords are attached.

My invention is illustrated in the accompanying drawings, in which like letters indicate like-parts.

Figure 1 is a side elevation of the bindingwire, showing the bends or curves. Fig. 2 is a side elevation of a signature with the wire lying in the folds. Fig. 3 is a perspective View of a number of signatures bound together.

A is the bindingwire, with bends or curves at a.

B represents the signature or signatures, with the back-cords b lying in the saw-cuts underneath the bends in the wires.

I use the following method of binding the signatures together: I place five needles, or as many as there are sawbuts, armed with twine or cords, in a suitable frame, the same distance apart as the curves in the wires and saw-cuts 0 in the backs of the signatures. The signatures are then taken one at a time and a wire placed in the center fold, so that the curves shall fall into the saw-cuts. They are then brought over the points of the needles. The points are entered into the saw-cuts and through the curves of the wires, and so on, one signature after another, untilthe signatures of the book have all been brought over the needles, which are then drawn through and the signatures secured to gether with the twine.

I am aware that prior to my invention Wire staples having twine rove around them to connect the signatures have been used; also, that corrugated and twisted wire pins with cord have been used to connect signatures, and that the leaves of books have been secured together by being mortised in the back and having needles held in the folds secured by cords or elastic straps. I therefore do not claim any of these as my invention but I What I do claim as my invention, and desir to secure by Letters Patent, is

In combination with book signatures having said saw-cuts' in the back, a continuous binding-wire lying in the folds of the signatures, and having curves or bends projecting into the saw-cuts, substantially as and for the purpose set forth.

WILLIAM I. BLAOKMAN.
